Hi, I live in the Chippenham area and we used to have good reception of all the multiplexchannels including SDN & BBCA. Recently SDN has moved to C48 which is adjacent to the BBCA mux on C49 and we now have appalling/ unwatchable reception on all program channels on C48 & C49 as evidenced by signal measurements giving good signal strength but very poor and highly variable signal quality for BOTH C48 & C49 (other muxes still give good reception).
I understand that in RF planning one never collocates transmissions on adjacent frequency bands on a given transmitter as this reduces the usable range on these bands arising from increased cross interference.
I would prefer not to have to move to satellite reception or internet to receive Freeview programs.
Why has this been done and are there any plans to move either of these muxes to other frequency bands in the near future to avoid this problem ?
